Application filed March 28, 1908., Serial no 42s,s'is.

Toall whom it may concern:

Be it known that I, SEVERINAS R. BEL- LANY,citizen of the United States, residing at Fruitvale, in the county of Alameda and 5 State of California, have invented new and "useful Im rovements in Centrifugal Filters,

of which t e following is a specification.

. My invention relates to a filteringappa ,ratus, and it is especially 'desi ned for. the purification of water, and other llquids.

It consists-in the combination of a seriesof revoluble perforated cylinders, with intermediate filtering media, and-means for discharging[ the filtered liquid from the exterior;

talso comprises details of construction "Zn-filter. Fig. 2' is -a section, online "of F1 1. I it is the object of myinvention to provide a means .for filtering water and-liquids under pressure, so that the work may be performed thoroughly, and at the same time quickly.

' As shown 'in theedrawing, A is a cupshaped receptacle having a shaft 2 which is turnable in suitable bearings, and to which power may be applied to rapidly rotate the receptacle-VA. This receptacle'is here'shown as contained inlan outer casing3. The-receptacle A has a convergent cap 4 which is screwed or otherwise secured upon M, the top of the receptacle A, with a suitable 35. water-tight gasket'fi. Within this receptacle A are a series of metal cylinders 6, spaced apart as shown, and each one perforated with holes. The upper portion, which is covered by the hood 4,'is correspondingly 40 convergent; and these perforated cylinders are made of decreasin height from the inner one to the outer one, thelatter havin a little greater-height: than the depth of t e @11 tainer 1 Through a pipe? li uir is admitted into the upper portion 8 of t e apparatus, and the supply is regulated by a rising and falling fioat 8, which moves in unison with the dis charge of the liquid from the chamber 8. The liquid passes fromthis chamber downward into the innermost of the perforated cylinders 6. Exterior to each of these cylinders is a filtering mediacf any suitable description. ent case, made of wire gauze 9, and the cov- 'ering of asbestos orother filtering medla as Specification of Letters Patent.

It may be, as shown in the,,pres'- Patented July 1,4, 1 808.

at 10; the filtering media-lying in each case,

contiguous to the inner cylinder, and the ,wiregauze between the filtering media and the cylinder next exterior thereto so as to form a support for the filter'propen.

The apparatus being revolved with any desired degree of rapidity, the water will be,

thrown out by centrifuglal force, passing through the holes in eac cylinder successively, and through the intermediate filters until it reaches a chamber 11 exterior'to the as Y outer one of the perforated cylinders. From this chamber the Water will be carried up between "the convergent cap 4- and an inner cap 12 which'forms a continuation from the" chamber A, and with an annular space hetween it'and the convergentcap 4; Cap '12 has a base flange with openings (1 for the passage of water to the Taforesaid space. This spac e'is-mai1 1tained by suitable knobs or projections asshown at 12 The water passing upwardthr'ough this annular space is delivered into a larger chamber 15 by means of pipes 'orpassages 14. From this outer re ceiver 15, it may be drawn through any suitable pipe or outlet 16. v

Having thus described my invention,- What IcIaimand desire tosecur'e by Letters Patent is, v

1. In a filtering apparatus, a vertically revoluble receptacle having an upwardly convergent cap, perforated metal cylinders concentric wit I one within the other, filtering media fixed between said cylinders, a" regulating floatcontainin g chamber connected with the interior of the inner perforated cylinder and having a means for supply, a chamber exterior to thefilters, passages through which the filtered water is delivered through the convergent hood ,an exterior receiving cha mber and means for withdrawing liquid therefrom; Q,- .-2. In an apparatus of the character dethe chamber and cap lying.

scribed, a vertically disposed i'chamber having a cone-shaped removable cap, a verticalshaft upon which said chamber is mounted and revoluble, a, series oferforated, openended cylinders fitting within the chamber and cone, and increasing in height from the outermost tothe innermost, filtering media occupying the space between said cylinders,-

a'supply pipe, a float chamber into which it epens, connection between said float champer and the: interior of the.innermost perjforated cylinder, a receiving chamber for filtered liquid be'tW'eQ-n the outermost per- 7 my hand. in presence of two subscribing witierated cylmder and the mtemor of the conmesses.
